UNITED STATES THOMAS WIGLE-Y, or BRIDGEPORT, CONNECTICUT.

- IMPRO VEM ENT IN CARRlAGE-LANTERNS.

Specification forming part of Letters Patent No. 133,735, dated December10, 1872.

To all whom it may concern:

Be it known that I, THOMAS WIG-LEY, of Bridgeport, in the county ofFairfield and State of Connecticut, have invented a certain Improvementin Vehicle-Lamps, of which the following is a specification:

My invention relates to the construction of that portion ofvehicle-lamps commonly known to the trade as the stem, or tail-and-stem,or tail-collar; and consists in spinning these parts from one piece ofmetal, the object of which is to dispense with the soldered joint at thejunction of the collar and stem, as now employed in the manufacture ofthe present style of vehicle-lamp. This joint-is liable to work looseowing to the constant shaking or jarring of the vehicle, and the stem tobecome not only loose andmar the finish of the lamp,

' but to frequently become detached and lost in the street when thevehicle is in motion; whereas in my invention this is obviated in makingthe collar and stem of-one continuous piece; at the same time a betterfinish is obtained.

inside stem or socket E'secured in the center of it. The stem in thiscase is formed on a tapering mandrel, and is then attached to thecollar, which has been previously spun upon the lathe. The stem or tailA, Fig. 1, of my invention is spun on a lathe with a sectional chuckfrom one piece of metal, and is soldered directly to the lower panel Fof the body of the lamp without the interposition of the'collar, as inthe present style. In order to give greater beauty of finish to 'thestem the sides of it are swelled out on the line a b, and are graduallycontracted toward the end or tip 0, and above the line a b they arecurved gracefully inward until the upper end is reached, where theyspread outward to form a broad base for the panel F to rest on.

In making the sides of the stem in the form above described, or in anyform where a portion of it is to be swelled out or increased in area, asectional chuck is to be used on the lathe, arranged so as tobe takenapart and Witnesses:
